Stupid question - do you have both auto-focus dials turn to AF and not manual? There's one on the body of the camera to the right side of the lens, approx 4 o'clock (if lens is facing you) and there's also a auto-focus switch on the lens itself. Check both places to make sure you have both turned on.
1- The contacts between this particular lens (I suppose your other lenses focus OK with this body) are dirty. You could try cleaning them with alcohol or a pencil eraser.
2- The focusing motor inside the lens is defective. In this case you would have to send it in for repair.
So I'd start with the cleaning. One more thing I'd try is to test it on another camera just to take your camera completely out of the equation.
